Reduced glycemia can arise from reduced rate of glucose
introduction to the blood, increased rate of glucose uptake by
tissues, or both.It is possible that at least the former mechanism
is involved in the reduced glycemic response to the soy
pretzel. The larger amount of total food in the stomach with the
soy pretzel may have slowed the transit time from stomach to
small intestine, reducing the rate of carbohydrate availability for
absorption. The addition of protein has been shown to slow the
rate of gastric emptying and, consequently, reduce postprandial
glycemia in glucose/gelatin-based beverages.
